[SIPForum-discussion] how PUBLISH message route to destination

[zan.chen]

hi all:

    I am confused with PUBLISH message. If i want to publish my own presence information, I  set the Request-URI of PUBLISH message to my AOR, if there is no pre-set route set, then how can send this message to ESC? Do  we need to know the ESC'S address first?

Thanks
